This mask utilizes end user supplied filter material, cut into 38mm/1.5'' disks.
It also utilizes a one way valve, which allows exhaled air to exit valve, instead of exiting through the filter, greatly increasing filter life.
One n95 mask can be cut up to make 5 filters.
Use any 10mm/3/8'' strap, and this valve from amazon...https://www.amazon.com/gp/product/B084BVQLBP/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I would also add some thin foam tape to the face/mask interface.
If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design.
Thanks, Enjoy!
